AGRICULTURAL IMPLEMENT.

Specification of Letters Patent.

Patented Oct. 2, 1906.

Application filed May 11,1906. Serial No. 316,385.

T 0 aZZ whom it may concern.-

Be it known that we, JEREMIAH CLARK MEssER and JEFFERSON CooK, citizensof the United States, residing at Buda, in the county of Hays and Stateof Texas, have invented a new and useful Agricultural Im lement, ofwhich the following is a speci cation.

This invention has reference to means for detachably holding a blade onan agricultural implement. Among its objects are the provision of novelmeans whereby the blade may be firmly held and yet readily detachedwithout the use of a wrench or tool of any sort and to provide aconstruction whereby continued use instead of loosening the blade willserve to tighten it on the shank or handle.

With the above and other objects in view the invention consists in thenovel parts and combination of parts hereinafter set forth, and pointedout in the claims, it being understood that various changes within thescope of the appended claims may be resorted to without departing fromthe principle of the invention or sacrificing any of its advantages.

In the specification and the accom anying drawings, forming a partthereof, tl e same reference characters are applied to the same partsthroughout.

In the drawings, Figure 1 is a sectional view of an implement of the hoetype, the section being taken in the plane of the handle. Fig. 2 is atransverse sectional view of the same. Fig. 3 is a pers ective viewshowing the blade and handle etached. Fig. 4 is a perspective viewshowing the handle-attaching means in connection with a tool of adifferent type.

Referring to the drawings by reference characters, 1 designates thegooseneck of a hoe, formed in accordance with this invention. The saidgooseneck is provided with a flat portion 2, the rear face of which isdesigned to contact with the upper front part of the hoe-blade.Projecting rearwardly from the lower part of the said flat portion 2 ofthe shank is a stud 3, which has a head 4 and a neck 5. The neck 5 is ofthe same dimension vertically as the head 4, but is narrowerhorizontally. Where the flat portion 2 joins the shank of the gooseneck,there is a shoulder 6, having a slot 7 therein. The blade of the hoe isprovided with an opening 8, throughwhich the head 4 of the stud 3 mayreadily be passed. Below the openin 8 is a wedge-shaped slot 9, ofsubstantial y the same width as the neck 5 of the stud. The upper partof the hoe-blade is notched at 10, the notch 10 being of substantiallythe same width as the shoulder 6.

To secure the hoe-blade on the gooseneck, it is only necessary tointroduce the stud 3 into the opening 8, the notch 10 at the same timereceiving the shoulder 6. The edge of the hoe is struck sharply u on theground or is struck by a piece of woo when the neck 5 of the stud 3 willpass into the wedge-shaped slot 9 in the hoe-blade and the upper part ofthe blade immediately beneath the notch 10 therein will enter the slot 7and the shoulder 6.

Since the slots 7 and 9 are each slightly smaller near the bottom, thefarther the hoeblade is driven upon the gooseneck the tighter it will beheld, the neck 5 being wedged into the notch 9 and the top of thehoe-blade adjacent the notch therein being wedged in the slot 7 in thegooseneck.

It will be observed that we provide means for fastening the blade to thegooseneck at two distinct points on the blade, one of these points beingnear the center of the hoe-blade and one at the upper central portionthereof. Further, the shoulder 6 provides means for holding thehoe-blade in alinement upon the gposeneck while it is being securedfirmly in p ace.

In Fig. 4 we have shown a plow-shovel 11, which is detachably securedupon a cultivator-foot 12 in the same manner as the hoeblade uponthegooseneck of the hoe.

My improved fastenin means dispenses with bolts and rivets and likefastenings and provides means whereby a hoe or other blade can beremoved from its shank by a blow of a stone or piece of wood and anotherblade substituted therefor as easily. A blade fastened in this manner issecured as firmly as if welded or riveted to the shank.

Having thus described the invention, what is claimed is- 1. In a deviceof the class described, the combination of a blade provided with awedge-shaped slot and a notch therein, and a shank formed to enter saidnotch and provided with a stud to enter the said Wedgeshaped slot.

2. In a device of the class described, the combination of a bladerovided with a wedge-shaped slot, a shanl i having atransversely-disposed Wedge-sha ed slot adapted to receive the edge of te blade, and a stud to enter the slot of the blade.

3. In a device of the class described, the combination of a blade havinga notched edge and a wedgeshaped slot, a shank hav ing atransversely-disposed Wedge-shaped slot adapted to enter the notch ofthe blade and receive the edge thereof, and a stud to enter theWedge-shaped slot of the blade.

4. In a device of the class described, a blade having its upper edgeprovided With a notch, a shank entering said notch, and means forsecuring the end of the shank to an intermediate part of the blade.

5. In combination, a blade having a notch at its top central portion andhaving a Wedgeshaped slot near its center, a shank having a fiat portionto rest upon the face of the blade and having a stud projectingtherefrom and formed with a shoulder at the top of said flat portion andWith a notch in said shoulder, the upper part of the blade at the baseof the upper notch therein being adapted to be secured in the notch inthe shoulder of the shank, and a stud being adapted to be re ceived inthe notch near the center of the blade.

In testimony that We claim the foregoing as our own We have heretoa'ffixed our signa- 3o tures in the presence of two Witnesses.
